Rayman for Nintendo DSi is a port of the original Rayman game which was released as a DSi-Ware title. As with Rayman Advance, it resembles the PC version most closely. The game can be purchased through the Nintendo eShop on the Nintendo 3DS.

Compared to the PC version of the original game, this port has been modified to be a lot easier in several ways. Rayman now starts off with 6 units of health (which is double the starting amount of health in the original) which can be extended to 10 with a Big Power. Lives can be obtained more frequently and only 50 Tings is required now instead of 100 for a new life. The number of continues has now been increased to 30 and the Photographer appears in several new locations. To make backtracking easier, the player can now skip to the next part of the player by pressing the select button. This only works in levels which have already been completed.

A noticeable issue is that whenever Rayman takes damage, he is now pushed back a lot further. While this can in some cases make it easier to quickly get away from the the enemy or object which inflicted the damage, it can also cause the player to quickly lose control over Rayman if he keeps getting pushed back and forth. This is most notably an issue in Allegro Presto. And Rayman's buffer time is shorter which makes Rayman lose more health and makes the game seem harder.

Other differences includes a few missing soundtracks and a lot of the sound effects, including Rayman's voice, being deeper in tone. Some of the textures have been updated, most notably in Band Land where the musical staves are now black instead of white. Some levels have received minor updates, such as Eat at Joe's having added dialogue where Joe the Extra-Terrestrial talks to Rayman before giving him the firefly. The ending has also been expanded compared to other versions. Another noteworthy difference is the option to have four letters in each save slot name instead of the usual three. The names can now also be changed manually from the pause menu, instead of having the player first copying and then renaming it. Another difference is that Rayman now retains the grimace power upon obtaining the running power, unlike other versions where it simply gets replaced. Both powers are still mapped to the same button, so the only way to perform the grimace is by doing so when not moving.

New to the game is a menu titled 'Anti Dark-Matters' which acts like a checklist to keep track of the player's progress on the game. As well as having check boxes for having beaten a world and having freed all the Electoons, the player is also rewarded for having completed a world, and ultimately the game, without the use of any continues. For each missions the player is awarded with a few lives.

Taking advantage of the DSi's camera, the Photographer now takes a picture of the player at every checkpoint, which is used to represent the saved game in the menu. The second screen is used to display a map of Rayman's immediate surroundings, which highlights where each checkpoint and exit sign is. The player can use the stylus to scroll through the entire level on the map.
